Disclaimer: I'm probably desensitized to this kinda stuff as I've read a LOT of trashy fantasy stories
The Writing: needs improvement? yes. Is it significantly better than other fantasy stories with similar ratings?(IMO) also yes
At least give some points for the originality and the fact that Chinese sayings are weird and clunky, at least the ones that I've heard.
The Art: is it bad? I've seen worse. It pulls off color a lot better than other Chinese comics. It also doesn't fall into the moe art style that has infected a lot of modern manga.
All i'm saying is that this deserves at least a 7.3 - 7.5. For reference, compare this to that to Isekai Nonbiri Nouka, which is just 0.03 points lower. That thing's writing is pretty trashy, not to mention unoriginal, and panders to indoor weebs a bit too much for my tastes. The art is also kinda mediocre for a black and white manga.
